Thanks for posting your query.
Most of the antiviral drugs, Antifungal like Griseofulvin
, Anti tuberculosis
like rifampin and other antibiotics like tetracycline
,aztreonam,azithromycin,doxycycline,amoxicillin/clavulanate,cefazolin etc can interact with Loestrin 24Fe and reduce its effects. Use alternative contraceptives while taking these antibiotics.
Hope it helps.
